    Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.

    Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances through tubes penetrating a tube sheet of a heat exchanger tube sheet, includes a smart lance tractor drive, a controller, and a tumble box connected to the controller operable to generate and/or distribute electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The smart tractor drive includes sensors for detection of mismatch between expected and actual lance positions, sense lance insertion distance and lance removal and provide automated drive reversal operation to remove blockages within tubes being cleaned.

    Abstract: An apparatus for driving a flexible lance hose into and out of tubes in a heat exchanger tube sheet includes a housing and an upper endless belt drive assembly and a lower endless belt drive assembly spaced apart by a gap for receiving a flexible lance hose therein. One of the drive assemblies is fixed to the housing. The other drive assembly is movable within the housing toward and away from the one endless belt drive assembly. The apparatus further includes a drive motor fastened to the housing configured to engage at least one of the upper and lower endless belts and drive a flexible lance hose disposed in the gap.
